176257-50-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 176257-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,2,5 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 176257-50:
(8*1)+(7*7)+(6*6)+(5*2)+(4*5)+(3*7)+(2*5)+(1*0)=154
154 % 10 = 4
So 176257-50-4 is a valid CAS Registry Number.

Glycosamino acids: New building blocks for combinatorial synthesis

McDevitt, Jason P.,Lansbury Jr., Peter T.

, p. 3818 - 3828 (2007/10/03)

In order to produce inexpensive, chemically diverse carbohydrate building blocks more amenable for use in combinatorial organic synthesis, amine and carboxylic acid functional groups were incorporated into several monosaccharides. A series of 12 new glycosamino acids was prepared from commercially available starting materials. Conventional peptide synthesis solution coupling techniques were used to ligate glycosamino acids, producing oligomeric 'glycotides'. Finally, a library of glycotides was produced by coupling of a glycosamino acid mixture to a rigid template.
